Application filed liovember'fl, 1924. Serial No. 752,014.

To all whom it may concern:

Be it known that we, MARSHALL W. GLEA- SON and CLARENCE G. MILLER, of the, borough of Brooklyn, county of Kings, city and State of New York, haveinvented certain new and useful Improvements in Glass Leers, of which the following is a specification.

particularly to an attachment therefor, the object being to produce such an attachment which can be removablyplaced and connected with an existing leer for the purpose of firing in colors on vitreous wares.

Our invention is shown in the accompanying drawings in which Figure 1 is a longitudinal side elevation, partly broken away to show interior details: Figure 2 is a front or end view, the upper door being closed and the lower door being shown open, and Figure 3 shows details of pans and connecting rod, in perspective. Similar reference characters refer to similar parts in the several views.

The body forms ,a chamber 1, rectangular incross section, and of a size suited for the opening of the leer proper, L, and consists preferably of galvanized sheet iron, strengthened and braced by a framework of iron, 2, and supported by several pairs of legs, 3, with rollers 3.

At the intake end doors, 4, 5, are provided: angles, 6, 7 are fastened to the bottom of the chamber to act as guides or rails for the transitory pans, 8: these pans are connected with eachother by links, 9, pivotally mounted near the end of one pan and engaging a notch,. 10, in the adjoining pan, as shown. Any other preferred way of joining the minor detai i A curtain, 11, of strips of asbestos, suspended from the roof of thechamber at the proper point conserves the heat coming from the leer L: one or more ventilators, .12, may be used for regulating the temperature within the chamber.- I

A removable rest, 13, for the loading of the pans with wares to be fired is connected to the body by hooks, 13' which slips over a rod, 14, fastened .to the body, 1."

A rod, 15, flattened and bent at right angles at one end, 15, and bifurcated at the Our invention relates to glass leers, more.

pans may be used, this being a other end 15 is adapted to draw the ans through the fchamber and intothe leer b means of the mechanism, M, in the leer. X simple means is shown for'drawing the pans into the leer; any other well known method may-be employed to suit the particular requirements as this detail is a minor one.

Such being the construction, the operation is as follows :--VVhen it is desired to firea group of wares which have been previouslydecorated, the attachment is rolled over and connected with the mouth of any leer L, which has its heating means, H, at or near the front and is also provided with the usual "rotary mechanism, M, to advance the pans through the leer, as is usual in glass annealing leers. Any opening or space between the mouth of the leer and the body of our improved attachment can be filled in or stopped oil with asbestos so that no heat will escape except through the chamber of the attachment.

The doors, 4, 5, are opened and secured in that position in any preferred way, and the pan rest, 13, placed in position, as shown. Wares to be fired are placed on the pan, and when ready, the rod, 15, is passed through the chamber and connected with the links, 9, on both sides of the pan the other end of the rod being flattened and bent at right angles engages the mechanism, M, of the leer by which the pan is slowly drawn toward the leer proper. Another pan is placed on the rest and filled with wares,

the links, 9,engage the notches, 10, and the pan will be drawn into the chamberby the pan just previously loaded, and the-operation is repeated indefinitely to conclusion,

.when the pan rest, 13, is removed and the doors, 4, 5, are closed.

As the open or loading endof the chamber is the coolest part of it, the ware entering there is'gradually warmed as it advances toward the leer, the curtain, 11, and

ventilators, 12, being used to regulate the degrees of heat. As the pans move very slowly, by the time they reach the leer proper the wares placed on them for fir-- in'g will havebeen sufiiciently preheated so through the leer until they reach the far end which iscool enough so that ware can b removed from the pans, as usual.

Such being our invention what we claim and desire to secure by Letters-Patent is:

l. A removable attachment to leers, composed of a body forming a chamber. one end of which is adapted to connect with the v mouth of a leer, means of closing the free end of said chamber and of interlocking pans adapted for transitory passage through said chamber.

2. A removable attachment for leers consisting of a body forming a chamber adapted for connecting with the mouth of a leer, of parallel rails at the bottom of said chamber, a series of interlocking pans to traverse said rails, of means for moving said pans in a direction toward said leer and of means for closing the free end of said chamber.

3. An attachment for leers consisting of a body having elongated chamber, open at one end and rovided with doors at the other end, means or regulating the temperature within said chamber, of parallel rails fastened to the floor of said chamber, and pans adapted for transitory passage through said chamber, and of means for drawing said pans through and away from said chamber to and through a leer to which said attachment has been connected.

4. A removable attachment to glass leers composed of a body forming an elongated chamber, one end of which is adapted to connect with the mouth of a leer, of parallel rails on the floor of said chamber, of interlocking pans traversing said rails and of means for moving said pans into and through said chamber.

In testimony whereof we have hereunto set our hands in the presence of two witnesses.
